Problems solved by technology
[0009] 1. The first damping element 92 and the second damping element 93 are not installed at the positions of the flow guides 911 of the two frames 91, therefore, when the fan wheels to which the two frames 91 belong are in motion, the first The first vibration damping element 92 and the second vibration damping element 93 still cannot comprehensively absorb or buffer the vibration transmitted from the flow guide 911 of the two frames 91, so that the second type of existing serial fan 9 is still possible will have a resonance effect
[0010] 2. The second type of existing series fan 9 must additionally set the first vibration damping element 92 and the second vibration damping element 93 between the two frames 91, compared with the aforementioned first type of existing series fan 9 The fan 8, the second type of the existing series fan 9 has more components, resulting in a relatively large increase in the complexity of assembly

A serial connection fan frame is used for solving the problem that an existing serial connection fan is limited in resonance effect. The serial connection fan frame comprises a first fan frame body and a second fan frame body, wherein the first fan frame body and the second fan frame body are in butt joint through a metal frame element which can serve as a part of the first fan frame body or / and the second fan frame body, and other parts of the first fan frame body and the second fan frame body are plastic frame elements. The first fan frame body and the second fan frame body are combined in a serial connection mode, stator sets and fan wheels are arranged to serve as a serial connection fan to use, the resonance effect generated when the serial connection fan works can be reduced by means of the metal frame element, noise is effectively lowered, and combination strength between the first fan frame body and the second fan frame body is improved.
Description
technical field [0001] The invention relates to a fan frame, in particular to a serial fan frame formed by connecting at least two fan frames in series. Background technique [0002] Please refer to figure 1 , which is the first existing series fan 8 disclosed in the patent case of China Taiwan Announcement No. I324504 "Vibration-proof Structure of Series Fan". A vibration-absorbing element 82 is arranged between the surfaces, and the shape of the vibration-absorbing element 82 corresponds to the joint surface shape other than the base 811 and the rib 812 of the two fan frames 81. When the two fan frames 81 are connected in series, the The vibration-absorbing element 82 absorbs, isolates and buffers the vibration fundamental frequency generated by the fan wheel rotors in the two fan frames 81 to avoid resonance effect. [0003] However, this first type of existing serial fan 8 has disadvantages as follows: [0004] 1. The vibration-absorbing element 82 is made of rubber, ...
